A thermoacoustic engine includes a first looped pipe provided with a motor configured to convert thermal energy into acoustic energy, a second looped pipe provided with a receiver configured to convert the acoustic energy converted by the motor into thermal energy, and a connecting straight pipe interconnecting the first and second looped. A loop length between one end and an opposite end of the second looped pipe is set to L, the one end and the opposite end being connected with the connecting straight pipe such that acoustic energy is transmitted from the one end to the opposite end. The receiver is disposed within the second looped pipe in a region separated from the one end toward the opposite end by L×(0.6-1).
